SFP 10Gb Port

[Hirad Rasoolinejad]

Hi everyone

Unfortunately, we have lots of services that connect using SFP 10Gb ethernet. We have huge traffic coming to our servers, and we need to process them and analyze network traffic based on transmit and receive. Prometheus and Node Exporter can't detect any SFP port. Is there any specific exporter? Do I need to change any configuration?
Thanks for your support

The node_exporter simply reports the contents of `/proc/net/dev` as metrics. If the network interface is missing from there, it's a kernel bug.

Also, can you provide more information about your host OS? How you are running the node_exporter, what version, etc.

Hi,

Are we talking about a standad network interface which shows up in the
OS as enSOMETHING? Then it should be covered by the kernel metrics which
node_exporter collects as part of netclass/netdev/netstat collectors
which are enabled by default.
We have no troubles monitoring our interfaces with 10G ports (or higher).

If this is some specialized hardware which is driven by a userspace
network stack or something, then things might be different

Can you share some more details how the interfaces look like in the
operating system and which metrics you are missing?


Kind regards,
Christian
